DUST=GUARD FOR CAR=AXLE BOXES.

SPECIFICATION forming part of Letters Patent No. 390,991, dated October9, 1888.

Application filed June 8,1888. Serial No. 276,503. (No model.)

To all whom it may concern.-

Be it known that I, J osEPHUs STIER, a citi zen of the United States,residing at Baltimore, in the State of Maryland, have invented 5 certainnew and useful Improvements in Dust- Guards for Oar-Axle Boxes, of whichthe following is a specification.

My invention relates to an improved dustguard for'ear-axle boxes. Theobject is to provide a simple dust-excluder for the rear side of thebox.

In the drawings herewith, Figure l is a view of the end of acar-axle anda longitudinal sec tion of the axle-box. Fig. 2 is an elevation showingthe rear sideof the box, the axle, and

the dust-guard. Fig. 3 is a view of the dustguard separate. Fig. 4 is anedge view of the same. Fig. 5 is a view of one section of the guard.Fig. 6 is a cross-section of the same.

The letter A designates the axle, and B the box. At the rear end, 0,thebox has agroove, d, which in the present instance opens at the top,and the dust-guard occupies this groove. 23 The improved dust-guard isdivided in two parts,f which at the point of joinder have ahalf-circular notch, h, (see Fig. 5,) to form, when the two parts arejoined, a hole for the axle, (see Fig. 3,) and each side of the notch h0 is provided with a tongue-and-groove connection,f g. This connectionallows the two parts to have a limited movement to and from each otherwithout thereby exposing an opening at each side of the said axle-hole.The

5 two part dust-guard surrounds the axle.

When the dust-guard is first placed on the axle, the tongue-andgrooveconnections are partly drawn out, and when by the turning of the axlethe half-circular notch h wears or en- 0 larges the two parts graduallyclose together, and the partly-drawn-ont tonguesf will enter farther inthe groovcsg. A spring, i, provided with a central coil and having hooksr" at its ends, extends across the edge of one part, g, of

5 the guard, with the coil of the spring connected.

to a groove in said part 9, and wires k, with eyes 70', attached to theother part of the guard, extend to and connect with the ends of the saidspring. Thus the spring t and the wires is form an elastic connection,which binds the two parts of the guard around the axle, and the guard,thus keptin place, excludes the dust from the box. The wires k may beattached in any suitable way.

My invention includes a groove, 1, on the edges of the guard, and theconstruction shown for the wire 70, whereby it forms a yoke and occupiesthe groove Z. The wire yoke k extends across the bottom and up eachside. (See Figs. 1 and 3.) At the top each end of the wire has a loop oreye, k, which connects with the said spring i, extending across theouter edge of one part, g. The wire it, surrounding three sides of theguard, serves as a yoke to bind the two parts of the dust-guardtogether,

and the spring 1', by drawing on the wire yoke, keeps the said two partsclose about the axle and constantly takes up the wear. Thus thedust-guard, as here described, is effectual to exclude dust, and also toconfine the lubri- 7o cator within the box.

The dust-board has sufficient movement up and down, and also sidewise,in the groove 01 to allow it to give to the play of the axle.

It is obvious that a dust-guard having these 7 features may enter andoccupy a groove, d, in the axle-box, which enters at the top, as hereshown, or a groove which enters at the vertical sides. 1

Having described my invention, I claim- The combination, with theaxle-box having groove (1, the axle A, and the tongue andgrooveddust-board consisting of the partsfg, provided with edge grooves, Z, ofthe yoke connecting said grooves Z, and having at its upper 85 ends eyesand the spring 1', having a central coil connected in a groove in thetop portion of the part 9, and provided with hooks i to connect with theeyes 7: of said yoke, substantially as specified.

In testimony whereof I affix my signature in the presence of twowitnesses.

JOSEPHUS STIER.
